Nemiah x Charge-M8

In most buildings, EV charging is a stranger. Different supplier, different dashboard, different bill, and no connection to the heating, lighting, or incoming supply it shares a meter with. That separation is manageable until charging load starts competing with everything else for the same capacity. Then it gets expensive, or it trips the building.

Our partnership with Charge-M8 is built to close that gap. Charge-M8 supplies EV charging hardware at scale, alongside its Libra Dynamic Load Balancer, which distributes available power across multiple chargepoints to avoid overloading a site's supply. We are integrating that hardware and Libra into cosmOS, our building management platform.

The outcome is straightforward: charging stops being a parallel system and becomes a managed part of the building. A few practical changes follow from that.

Load is coordinated, not only balanced across chargers. If HVAC is drawing heavily at two in the afternoon, cosmOS can ease charging rates for a short window rather than tripping a breaker or pushing the site into a costly demand charge, then increase rates again as the peak passes.

Pricing can also move with conditions. Because cosmOS already sees grid signals, on-site generation and site demand, charging can be priced dynamically rather than at a flat rate, reflecting what energy actually costs at the moment it is drawn. At Leigh Works, demonstrator scenarios have shown how this approach can reduce peak-time charging pressure while preserving useful charging throughput for users.

This matters most for sites where charging demand is growing faster than spare electrical capacity. Without coordination, operators are often forced into expensive upgrades earlier than expected, even though much of the issue is timing rather than total daily usage. By orchestrating charging against wider building demand, cosmOS and Charge-M8 help defer avoidable upgrade costs while maintaining a better user experience for staff, fleets and visitors.

Most importantly, charging sits inside the building's wider energy and carbon picture rather than outside it: one dataset, one platform, one view for whoever runs the site. A facilities manager stops cross-referencing a charger portal against an energy dashboard against a spreadsheet and starts using a system that already understands how the chargepoints, the building and the grid relate to each other.

The first deployment stage is underway through the Leigh Works demonstrator, combining Charge-M8 hardware and cosmOS controls in a live operating environment. As fleets electrify and workplace charging demand climbs, buildings that treat chargepoints as part of an intelligent energy system will run them more reliably and at lower cost than buildings running isolated infrastructure with no view past the car park.

An easy route to realtime energy monitoring

With Libra installs starting from £1,000 per grid connection, the Charge-M8 partnership also opens up a simple route to realtime energy monitoring for sites that don't have it. Libra's load balancing relies on real-time data from the building's supply, and that data is now available in cosmOS as well. This is a quick way to get visibility of energy use and grid conditions without a separate metering project.
